the inner core
there are many reasons for heat in earths crust. like the friction between rock masses during movements of earths crust. there may also be heat left over from the original heat of earths interior. but the main reason for heat in earths crust is radioactive elements. they give off energy that can be absorbed as heat. some radioactive elements include uranium, thorium, and a form of potassium.
Geothermal Energy
The sun
it comes from earths interior heat
the inner core
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
sunlight and meteor impacts

Geothermal Energy
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
The sun
False.
False.
it comes from earths interior heat
It's called the convection current.
the heat and pressure in the interior is not designed to sustain human life
